Heat transfer during formation massive ingots.

Fundamental activity at the Institute of Metallurgy and Materials Science
(structure formation modelling for multi-layers materials)

Some thermodynamic models are working out for structure formation:

a/ in the diffusion interconnection formed during isothermal soldering,
A competition between formation the stable intermetallic phases and meta-stable intermetallic phases is justified thermodynamically in the model. The phenomena of dissolution, solidification and the first solid / solid reaction are taken into account in the model. An occurrence of the undercooled peritectic reactions is justified. Some equations for the solute redistribution are proposed for each formed joint sub-layer.

b/ in the coating deposited by the D-gun method with partial melting of sprayed particles,
A competition between equilibrium and non-equilibrium phases formation is justified thermodynamically in the model delivered for the micro scale. It is also shown that the single particle deposited by D-gun spraying onto the steel substrate is subjected to partial melting. Some intermetallic phases solidification within the formed sub-layers is described. It is confirmed that the single particle behaviour corresponds well to behaviour of the diffusion interconnection during its solidification. An analysis of thermal gradients and growth rates allows for justifying the structural asymmetry of this kind of interconnection. The boron influence on the interconnection adhesion improvement is also described.

c/ in the protective coating which are obtained by the hot dip galvanizing,
Some thermodynamic conditions required by the protective coating formation are delivered. The appearing phases are treated as the result of peritectic reactions. An amount of growing phase is described mathematically. The role of the flux is taken into account as the third element for the Fe-Zn system. The behaviour of the flux which is transformed into a gas and evaporates in the course of nature is also described.

d/ in the single crystals strengthened by some layers of the intermetallic compound,
The structure of layers strengthening the single crystal is defined. A new, unknown up to date, criterion for structure selection within the layers is formulated based on the thermodynamics of irreversible processes. It takes into account the condition of minimum entropy production. A state of marginal stability is applied to the description of structural transformation of the irregular structure into the regular structure inside the strengthening layer.
